SPECIFICATION forming part of Letters Patent No. 265,370, dated October3, 1882,

Application filed August 14, 1882.

To all whom it may concern:

Be it known that I, ELI J. BARR, of Litiz, in the county of Lancaster,and in the State of Pennsylvania, have invented certain new and usefulImprovements in Grain -Ventilators; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, ref-- erencebeing bad to the accompanying drawings, and to the letters of referencemarked thereon, making a part of this specification.

This invention has for its object to provide certain improved means forcooling and ventilating grain in bins, it it should become heated,without removing or disturbing it. These objects I attain by theapparatus illustrated in bottom, 0, by means of which they communicutewith each other. The foraminous tube should be provided with a suitablecap at the upper end, or otherwise closed at such end, and theimperforate tube provided with an opening at the top for the admissionof air.

(No model.)

In the modification shown in Fig. 2 of the d rawing, the two tubes areconcentric, the imperforate tube being within the foraminous tube. Theconical bottom in this case is attached to the outer tube, and the lowerend of the inner tube opens directly into said bottom, which isperforated. as indicated.

In employing my improved device it is inserted into the body of grain,the conical bottom permitting it to enter freely. When inserted air isintroduced into the imperforate tube, and, passing downward, enters thetoraminous tube at the bottom, by which it is distributed throughout thegrain, cooling and ventilating it thoroughly.

The device may be inserted vertically or in any other direction into thegrain.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, 1s

Theimproved apparatus forcoolingand ventilating grain, consisting of aforaminous and an imperforate tube connected at their lower ends by aconical point, and adapted to be inserted in a body of grain,substantially as specified.

In testimony whereof I affix my signature, in presence of two witnesses,this 20th day of July, 1882.

ELI J. BARR.
